This commit enables a bunch of unrelated ruff rules, which only require minimal changes to the code base to enable them. The rules enabled by this commit are: - check the use of datetime objects without timezone (DTZ005) - check the performance of try-except in loops (PERF203) - check the number of function arguments (PLR0913) - check for mutable class defaults (RUF012) - check for the use of secure hashing algorithms (S324) - check for raising base exceptions (TRY002) - check for raising other exceptions where TypeErrors should be raised (TRY004) |

0 A.D. Font Builder
The Font Builder generates pre-rendered font glyphs for use in the game engine. Its output for each
font consists of an 8-bit greyscale PNG image and a descriptor .fnt file that describes and locates
each individual glyph in the image (see fileformat.txt
for details).
See the wiki page for more information:
http://trac.wildfiregames.com/wiki/Font_Builder2
Prerequisites
The main prerequisite for the fontbuilder is the Cairo imaging library and its Python bindings,
PyCairo. On most Linux distributions, this should be merely a matter of installing a package (e.g.
python3-cairo
for Debian/Ubuntu), but on Windows it's more involved.
We'll demonstrate the process for Windows 32-bit first. Grab a Win32 binary for PyCairo from
http://ftp.gnome.org/pub/GNOME/binaries/win32/pycairo/1.8/
and install it using the installer. There are installers available for Python versions 2.6 and 2.7. The installer extracts the necessary files into Lib\site-packages\cairo within your Python installation directory.
Next is Cairo itself, and some dependencies which are required for Cairo to work. Head to
http://ftp.gnome.org/pub/gnome/binaries/win32/dependencies/
and get the following binaries. Listed next to each are their version numbers at the time of writing; these may vary over time, so be adaptive!
- Cairo (cairo_1.8.10-3_win32.zip)
- Fontconfig (fontconfig_2.8.0-2_win32.zip)
- Freetype (freetype_2.4.4-1_win32.zip)
- Expat (expat_2.0.1-1_win32.zip)
- libpng (libpng_1.4.3-1_win32.zip)
- zlib (zlib_1.2.5-2_win32.zip).
Each ZIP file will contain a bin subfolder with a DLL file in it. Put the following DLLs in
Lib\site-packages\cairo
within your Python installation:
libcairo-2.dll (from cairo_1.8.10-3_win32.zip)
libfontconfig-1.dll (from fontconfig_2.8.0-2_win32.zip)
freetype6.dll (from freetype_2.4.4-1_win32.zip)
libexpat-1.dll (from expat_2.0.1-1_win32.zip)
libpng14-14.dll (from libpng_1.4.3-1_win32.zip)
zlib1.dll (from zlib_1.2.5-2_win32.zip)
You should be all set now. To test whether PyCairo installed successfully, try running the following command on a command line:
python -c "import cairo"
If it doesn't complain, then it's installed successfully.
On Windows 64-bit, the process is similar, but no pre-built PyCairo executable appears to be available from Gnome at the time of writing. Instead, you can install PyGTK+ for 64-bit Windows, which includes Cairo, PyCairo, and the same set of dependencies. See this page for details:
http://www.pygtk.org/downloads.html
Running
Running the font-builder is fairly straight-forward; there are no configuration options. One caveat is that you must run it from its own directory as the current directory.
python fontbuilder.py
This will generate the output .png and .fnt files straight into the binaries/data/mods/mod/fonts
directory, ready for in-game use.
